The Christian cross folds into a cube.
Cubes aren't evil, evil is evil. Hurting children is evil, sacred geometry is appreciation for creation.
Narcissism, egotism, sadism are evil.
Life is not black and white, use discernment, not snap judgements.
Also, there are more cults than just "Luciferianism" even though that is maybe the eldest Phoenician religion. It's really "Astro Theology", consult Gnostic Texts for more.
Christianity, Judaism, Islam, Hinduism…Astro-theology with different dogmas.
Here's what matters: God's law is love, don't be cruel.
